Battaash eased to victory to become the first horse to claim back-to-back wins in the Group Two King George Stakes at Goodwood.
The pre-race 8-11 favourite ridden by Jim Crowley finished ahead of two previous winners - Take Cover and Muthmir.
"It was pretty special, he is some horse," said trainer Charlie Hills.
"Jim looked in control but his a class above. I am so please the way he is behaving and he is improving."
Hills told ITV: "Racing does horses so much good and he has confidence in the people looking after him, they have a great relationship."
Crowley described Battaash's speed as being like the "Batmobile" and an "unreal machine".
"He dragged me to the front today," said Crowley "He is so enthusiastic. There is no horse fast enough in Europe, it was a great performance.
"When the gates open, it is a buzz riding this horse. It is a great pleasure winning with him."

On his day, Battaash must be as good a speedster as there is in the world, and this was certainly one of those days.
He was absolutely in the right frame of mind. When Jim Crowley said 'go', my goodness he went. The gallant runner-up, Take Cover, may be 11, but he's won twice and now been second twice, so can be considered a pretty decent yardstick, and he was emphatically swept aside.
The result was a notable one for Charlie Hills whose season thus far has been a little patchy.
